Problems solved by technology

These traditional transmissions have certain disadvantages, such as: ①Manual transmission requires the driver's manpower to operate, which increases the driver's operational difficulty and labor intensity, especially for urban public transport buses, and the ride comfort and comfort of the vehicle depend on The driver's control level; ②Although the automatic variable transmission can reduce the labor intensity of the driver, its fuel consumption is 10-20% higher than that of the manual transmission; ③Although the automatic continuously variable transmission can improve the comfort and smoothness of the vehicle , but its comprehensive transmission efficiency is low, and its fuel economy is worse than that of an automatic stepped transmission

Abstract

This invention relates to electrical gear drive device with braking and recycling function and relates to one electrical adjusting stepless gear, wherein, The device comprises clutch, motor fly wheel, double rotor gear and electrical liquid braking; the double electrical gear inner rotor end is connected to eh motor fly wheel; the one end of the middle rooter is connected to the clutch passive disc bus; the electrical liquid braking device is connected to motor fly wheel through gear or to the motor curved axis; the said middle rotor is connected to the gear output axis through gear.

Description

technical field [0001] The invention relates to an electronically controlled speed-adjusting automatic stepless electric transmission for vehicles, in particular to an automatic stepless electric transmission for vehicles with the functions of generating electricity by an internal motor and directly transmitting power. Background technique [0002] As a key component of any vehicle, transmissions have been used in a variety of vehicles since the dawn of the motor vehicle. Conventional transmissions that have been widely used can be classified into manual transmissions and automatic transmissions, or into mechanical transmissions and hydraulic transmissions. Manual transmissions are all stepped transmissions, while automatic transmissions can also be divided into stepped transmissions and continuously variable transmissions, and automatic continuously variable transmissions for vehicles are all hydraulic transmissions. These traditional transmissions have certain disadvantag...
